WHEEL FULLER.

Original application flied March 3, 1928, Serial No. 91,978. Divided andthis application filed Augult 18, 1926. Serial No. 130,073.

This is a divisional application of my copending application bearingSerial No. 91,979, filed March 3, 1926.

The present invention relates to new improvements in wheel pullers andhas for its principal object to provide a simple and-ellicient devicefor facilitating the removal of a wheel from the shaft on which the sameis keyed or mounted.

One of the important objects of the present invention is to provide awheel uller of the above mentioned character which may be readily andeasily set up in position for use and which will prevent any danger ofthe wheel which is being removed from its shaft becoming broken duringthe removal operation.

A still further object is to provide a wheel puller of the abovementioned character which is strong and durable, inexpensive and furtherwell adapted for the purpose for which it is designed.

Other objects and advantages of this invention will become apparentduring the course of the following description.

In the accompanying drawing forming part of this specification and inwhich like numerals are employed to designate like parts throughout thesame:

Figure 1 is'a perspective view of the wheel puller embodying myinvention showing the same in the act of removing the wheel from itsshaft.

Figure 2 is an end elevation partly in section.

Figure 3 is an enlarged fragmentary inside elevation showing the bosslike member and the adjacent portions of the channelshaped arms whichradiate therefrom, and also illustrating the pointed end of the screw,and v Figure 4 is a fragmentary detail sectional view of the boss-likemember showing a portion of the shaft-engaging screw threadedtherethrough.

In the drawing in which is'shown for purposes of illustration thepreferred embodiment of my invention, the numeral 1 designates generallythe wheel puller, the same comprising a boss-like member 2 which isrovided with an internally threaded bore 3 or a purpose to be presentlymade apparent.

A plurality of channel-shaped arms such as are shown at 4 extendradially from the boss-like member 2 and in the present instance, threeof such arms are illustrated. The boss-like member 2 is provided withradially disposed extensions 5 which are .formed'solid with the adjacentportions of the respective channel-shaped arms 4:, and as clearly shownin Fig. 3 of the drawing. The outer face of the boss 2 as well as theextensions 5 are flush with the free edges of the arms of thechannel-shaped members, this is clearly shown in Figure 4. Thisconstruction will provide a reinforcing means for the boss and willprevent any possible danger of the arms buckling or otherwise becomingbent due to the strain placed upon the device when in use.

A series of registering openings 6 are arranged in the sides of therespective chan nel-shaped radially extending arms 4 and as clearlyshown in Fig. 1 of the drawings, these openings are arranged in spacedrelation. The purpose of these openings will also be hereinafter morefully described.

A hook designated generally by the numeral 7 is associated with each ofthe radially extending arms 4 and to this end, the shank portion of eachhook is twisted as at 8 and an eye member 9 is formed on the inner endof each of these shanks. The eye members of the hooks are adapted to bedisposed between the sides of the respective channel-shaped arms 4:. Abolt 10 extends throughone pair of registering openings 6 formed in theside of each of the channelshaped arms 4 and also through the respectiveeye members of the hooks, a nut 11 be ing threaded on the threaded endof the bolt for maintaining the same in position against accidentaldisplacement.

In this manner, the inner ends of the shank portions of the hooks willbe pivotally supported between the ends of the respective channel-shapedarm members so that the hooks may be formed into an outer engagementwith the wheel or pulley which is to be removed from its shaft on whichthe same has become stuck. The provision of the series of spacedopenings in each of the radially extending arms enables the inner endsof the hooks to be adjustably secured whereby the hooks may be adjustedto accommodate the various sizes of Wheels or pulleys which are to beremoved.

An elongated screw 12 is threaded through the internally threaded bore 3of the boss-like member 2 and the inner end thereof is tapered toprovide a slia'l'lwugagiug point 1 A tool-engaging portion 11 is formedon the outer end of the screw 19 and in the present instance, saidportion is substantially rectangular and shaped to accommodate a wrench.

The use of the wheel puller as above described may be briefly stated asfollows:

The parts so arranged as shown in Fig. 1 of the drawings so that theouter ends of the hooks will engage the innermost side of the wheel orpulley 15 which has become stuck on its shaft 16. The pointed end 13 ofthe screw 12 is placed in engagement with the outer end of the shaft.The screw 12 is then rotated in one direction so as to cause theboss-like member 2 and the radially ex-. tending arms 4 associatedtherewith to move outwardly and simultaneously cause the wheel 15 toalso move outwardly whereby the same will be disengaged from the shaft16.

It will thus be seen from the foregoing description, that I haveprovided a highly novel and simple device for facilitating the removalof wheels from their shafts without any difiieulty, and further withoutany danger of the wheel becoming broken or otherwise damaged. Theprovision of a wheel puller of the above mentioned character will saveconsiderable time and labor and due to its simplicity, it can be readilyand easily set up in position for use and furthermore can be readilyadjusted to accommodate wheels of various diameters.

While I have shown the preferred embodiment of my invention, it is to beunderstood that various changes in the size, shape and arrangement ofparts may be resorted to without departing from' the spirit ofsacrificing any of the advantages of the appended claim.

What I claim is:

A wheel remover comprising in combination an internally threaded solidboss-like member, a screw threaded therethrough, a plurality ofchanneled arms extending radially from the boss like member similar tothe spokes of a wheel, the outer face of the bot tom of the channelshaped arms lying flush with the outer face of the boss like member, theouter edges of the sides of the channel arms lying in the same planewith the inner face of the boss like member, there being radialextensions formed on the boss like member and being formed solid withthe adjacent portions of the respectively channeled arms, the innerfaces of the radial extensions lying in the same plane with the edges ofthe channel arms and the inner face of the boss like member, wheelengaging hooks, an eye member formed on the inner end of the shank ofeach hook and disposed between the sides of the respective channeledarms, and a pivot member extending through the sides of each of thechannel arms and through the respective eye members of the respectivehooks.

In testimony whereof I afiixmy signature.
